Gefran 1300 Microprocessor Controller

Microprocessor controllers 48x96 built with SMT technology.Complete operator interface protected by Lexan membrane to guarantee an IP65 faceplate protection level.Composed of 4 keys double 4-digit green LED display, 4 red signals LED for the 4 relay-logic outputs and 3 additional LED with programmable function to signal the instrument various function states.The main input for the variable to be controlled is universal and allows connection of a wide variety of signals. Thermocouples, resistance thermometers, Thermistor and normalized linear inputs all with possibility of custom linearization set from the faceplate. Input type is selected entirely from the faceplate and requires no external adapter shunts dividers.

Other Details:
 

• Output (24VDC, 30mA max.)
• An auxiliary analogue input is available for a current transformer input.
• The instrument has a double control output that is 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 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).
• The programming of the instrument is simplified by the grouping of the parameters into function blocks.

Specifications:
 

• Thermocouples of types J, K, N, S, R, T
• Resistance thermometer Pt100 (3-wire)
• Linear inputs: 0-50mV, 10-50mV keyboard definable 2-10V, 0-10V, 0-20mA, 4-20mA with an external shunt.
