Gefran 1000-R0-1R-0-1 Controller

The Gefran 1000-R0-1R-0-1 is a microprocessor controller in 48×96 (1/8 DIN) format (the 1000 family also includes the 1001 and 1101, in 96×96 / 1/4 DIN format), manufactured using SMT.

The 1000 family provides an operator interface with a Lexan membrane faceplate (IP54 frontal protection), 3 keys, two green LED displays with 3 digits (4 digits for 1001 and 1101), red LED indicators for the 3 alarm relay outputs, and a green LED for the main control output.

The main input for the control variable is universal and can connect: thermocouples of types J, K, N, S, R, T; Pt100 resistance thermometers (3-wire); and linear inputs of 0–50mV, 10–50mV, keyboard-definable 2–10V, 0–10V, 0–20mA, or 4–20mA with an external shunt. There is an offset function on the input signal. An auxiliary analog input is available for a current transformer.

The instrument has a double control output, both relay (5A, 250VAC at cosφ=1) and static (24Vdc, max 20mA), and up to a maximum of 3 alarm relay outputs (3A, 250VAC). Alternatively, the control output can be analog (0–20mA, 4–20mA, or 0–10V, 2–10V). The optional communications port can be current loop or RS485 with GEFRAN (Cencal) protocol, maximum speed 9600 baud (RS485).

Programming is simplified by grouping the parameters into function blocks. Access to configuration parameters is protected by a hardware jumper, and different values of a protection code can restrict the number of parameters that can be displayed and modified by the user.
