Microprocessor Setpoint Programmer & Controller – 48x48 mm (1/16 DIN)

Built using SMT technology, this compact controller offers a complete operator interface protected by a Lexan membrane with IP65 front panel protection.

Key Features

• Interface & Indicators: 4 keys, two 4-digit green LED displays, 4 red LEDs for relay/logic outputs, and 3 programmable LEDs for operational status.
• Universal Input: Accepts thermocouples, RTDs, thermistors, linear signals, and potentiometers. Fully configurable via keypad—no external shunts or adapters needed. Supports custom linearization and two-point input correction.
• Auxiliary & Digital Inputs:
  • Isolated auxiliary analog input configurable as linear, potentiometer, or current transformer.
  • Two isolated digital inputs for program commands (start, stop, reset, program selection, step execution).
• Outputs:
  • Up to 4 configurable outputs (relay 5A/250V or logic 11Vdc/20mA).
  • Up to 2 isolated analog outputs (voltage/current).
  • Additional isolated output (10 or 24Vdc, 30 mA max) to power external devices.
• Control & Alarms:
  • Two independent PID loops for heat/cool control.
  • Three fully configurable alarms.
  • Heater break or short-circuit probe detection.
  • Local/Remote setpoint, Auto/Manual modes, self-tuning, and soft-start.
• Programming & Operation:
  • Up to 12–16 steps organized into 4 programs, each with setpoint ramp & hold, interlocks, and event outputs.
  • Simple menu-driven configuration using function blocks (CFG = control, Inp = input, Out = output).
  • Automatic display of relevant parameters based on hardware.
  • Second setpoint can be retransmitted to a slave controller with shared time base.
• Communication:
  • RS485 (RS232C compatible) with MODBUS RTU and CENCAL (Gefran) protocols.
  • Enables online monitoring, parameter modification, and direct control.
• Programming Kit: Optional PC kit with Windows software and connection cable (Data Sheet code 80021).

Performance

• Input acquisition every 120 ms; 30,000-step resolution.
• Dual displays for real-time monitoring and adjustment.
