Gefran 1000 (1/8 DIN) controllers are microprocessor instruments with a 48x96 format, and possessing a SMT technology. This 1000 controller is among a family of products, by Gefran, that provide complete operator interface. Gefran Instruments all have a Lexan membrane faceplate, to give IP54 frontal protection. Furthermore, Gefran’s Universal input provides the possibility to connect many types of sensors:
Thermocouple Calibrations are type J, K, R, S, T, B, E, N.
An auxiliary analogue input is also available for a current transformer input. Controllers’ have a double control output with both relay (5A, 250Vac at cosφ =1) and static (24Vdc, max.20mA) for up to a maximum of 3 alarm relay outputs (3A, 250Vac).
Sensor configuration is preformed from faceplate interface, of which, no external shunts or adapters are required. Programming procedures are facilitated by grouping parameters in function blocks (CFG for the control parameters, INP for the inputs, OUT for the outputs) Furthermore, the possibility of selecting a simplified menu for entering the most frequently used parameters is also available. Consequently, a programming kit for PC is also available to facilitate the configuration a step further.
