Product details

Overview

The 140CPU11302: Two serial ports — one Modbus RS232 and one Modbus Plus — connect the processor to the control network, supporting up to 63 distributed drops and 500 I/O words per network. The module draws 3.9 W from the Quantum backplane.

Integration

The processor mounts in a Quantum rack (PCE format) and is programmed via ProWORX 32 or Concept software. The onboard 3 V Lithium battery (1.2 Ah, 10-year life) retains RAM and real-time clock; expect a clock drift of ±8 s/day at 0...60 °C. Watchdog timer is set at 250 ms.
