Single Point
Trip Amplifier

 

This unit provides relay volt-free contacts which change state when the input signal passes an adjustable reference set-point. The relay may be set to operate when the signal is either higher or lower than the set point.

Dual Point
Trip Amplifier

This unit provides relay outputs which change state when the input signals (current or voltage) pass the points set on the front panel controls. The relays may be set to operate when the signals are either higher or lower than the set points. Relay outputs for each channel are in the form of a single pole change-over plus a normally open contact. Channels may be interlocked e.g. to for use in tank filling pump control. A transducer power supply is provided as standard.

Integrator

…or Analogue to Frequency Converter, this unit will convert a voltage or current input signal into pulses with respect to time; the pulse rate being proportional to the magnitude of the input signal.

Analogue
Summator /
Averager

This unit will sum together - or subtract - up to six voltage or current input signals. The output signal may be current or voltage and will be proportional to the sum or difference of the input signals. Inputs signals may represent different ranges and be of different types (e.g. current / voltage, true or raised zero etc.). This unit will perform an averaging function with equal input ranges.

Low / High
Signal Selectors

Provides a current or voltage outputs which are equal to the lowest (low selector) or highest (high selector) of up to six input signals. Input signals may be current or voltage but must be of the same type and span and must be able to share a single common line. NB a solution to this limitation would be to isolate each input using the 107-3A isolator.

Comparator

Compares two input signals and provides a relay output which changes state when the signals differ by an amount set by a front panel control. The relays each provide one change-over and one normally open contact. One relay operates when input A is greater than input B, the other when input B is greater than input A.

Digital
Divider

This unit provides an output which is the frequency of the input signal divided by a user adjustable integer. Inputs may be contact closure, change-over contacts, voltage level change, open collector or proximity switch. The output types include electromechanical counter, open collector, relay or voltage pulse. The unit can provide a transducer power supply. Two versions are available.
The two decade has a maximum division of 99. The four decade unit has a division of 9999 and further multipliers of x0.1 or x0.01 available.

Frequency
Scaler

This unit provides an output which is the frequency of the input signal divided by a user adjustable non-integer number. Inputs and outputs are as for the Digital Divider. Output Frequency=Input Frequency × R ÷ N ÷ D where R=0.000 to 0.9999, N is any integer from 1 to 9999 and D=1, 10 or 100.

Digital
Lineariser

(or function generator) This unit will accept a voltage, current or resistance input and provide an isolated current or voltage output which can follow any desired pre-programmed law. An optional multiplier input enables the output to be multiplied by an external variable.

Pulse
Isolator

This unit will condition and isolate a variety of input signal types and provide a clean, optically isolated and shaped output. Inputs may be contact closure, change-over contacts, voltage level change, open collector or proximity switch. The output types include electromechanical counter, open collector, relay or voltage pulse. The unit can provide a transducer power supply.

Pulse
Summator

Up to five digital (pulse) input signals may be summed to provide an output signal which equals the sum of the input pulses. An optional version operates as an adder / subtractor. Standard inputs (24V pulse) are optically isolated; other types of input catered for are volt-free contacts and externally isolated TTL or CMOS signals. Output options include open collector and electro-mechanical counter.

Status to Analogue Converter

Provides an analogue output which is proportional to the number of active inputs. Each unit will accept up to five inputs but multiple units (current output) may be connected in parallel. The number of input signals required for full scale output is set by internal switches. e.g. to provide a full scale output with 15 input signals present, three Status to Analogue Converters would be required, each set for 15 inputs.

Applications include providing a signal to a dosing pump proportional to the number of guns being operated in a spray booth for overspray paint reclamation.

Raise~Lower
(Set-point) & Ramp Generator
(programmable)

 

A versatile programmable instrument which may be configured either as a Ramp Generator or a Raise Lower device. Control of the output signal is provided by three inputs; Start/Raise, Stop/Lower and Reset. Optional PC software provides user selection of all functions except output signal rise and fall times which are user selectable by internal switches (NB may be supplied preconfigured to required settings without any user programming required).
