1001 Configurable controllers Specifications:

Gefran 1001 controllers are microprocessor instruments with a 96x96 (1/4 DIN) format for models using SMT. The 1000 family of controllers provide a complete operator interface, with a Lexan membrane faceplate to give IP54 frontal protection that has 3 keys, two green LED displays with 4 digits, and red LED indicators for the 3 alarm relay outputs and a green LED for the main control output. 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.

• Resistance thermometer Pt100 (3-wire)
• Linear signals: 0-50mV, 10-50mV keyboard definable 2-10V, 0-10V, 0-20mA, 4-20mA with an external shunt.

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).

Alternatively, the control output can be analogue (0-20mA, 4-20mA or 0-10V, 2-10V). The optional communications port can be Current Loop, or RS485 with GEFRAN (Cencal) protocol with a maximum speed of 9600 baud (RS485). Consequently, a programming kit for PC is also available to facilitate the configuration a step further.
