La description

Microprocessor controller, 48x96 (1/8 DIN) format for model 1000 and 96x96 (1/4 DIN) format for models 1001 and 1101 manufactured 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 3 (1000) or 4 (1001 and 1101) digits, and 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 provides the possibility of connecting different types of signal: 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. 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 cos&phi, =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. Access to the configuration parameters is protected by a hardware jumper and different values of a protection code can be used to restrict the number of parameters that can be displayed and modified by the user.
  • Inputs for thermocouples and resistance thermometers completely configurable from the faceplate
  • Offset function on the input signal
  • Relay, mA or logic main output
  • Between 1 and 3 configurable alarms
  • Auxiliary input for C.T.
  • Alarm for opencircuit load or shortcircuit probe
  • PD alarm output configurable for cooling
  • Self-tuning/Auto-tuning, Soft-start, bumpless Man/Auto transfer
  • Serial line: optoisolated 4-wires
