Digital I/O module PD3120

FieldbusdistributedPLC

This module must only be used to replace defective modules in an existing installation. For new installations, please use PD 820 instead The module is an intelligent module, provided with 16 input/output channels for 24 VDC and an internal user programmable Calculator for local control. Each channel has pulse and one-shot output, current measuring and overload protection. Each input has pulse counting, max 50 Hz and measures operating time. All outputs have test of single as well as double feed-back signals. Supply voltage: 24 V DC. * 16 Input/Output Channels (24 VDC) * Pulse or Contact Counting * Pulse and one-shot on all outputs * Output Feedback Facility * Automatic Output Functions * Overload Protection * Current measuring on each output * Programmable Calculator * Continuous Selftest * P-NET Fieldbus Communication * Watch Dog Timer * Rail mounting module (DIN / EN) * EMC approved (89/336/EEC) The PD 3120 Digital I/O Module is one of a collection of distributed process control units, intended for use within the P-NET Fieldbus system. It provides a versatile interface between valves, switches, pulses, lamps, alarms, motors, level detectors, etc., and distributed master control computers. The module possesses a programmable Calculator, which can be purpose programmed to control the digital outputs and monitor the digital inputs. The Calculator operates with different types of variables, such as reals, integers, bytes, booleans, timers and arrays. With the utilization of user programmes, application specific functions, such as digital control loop and PLC functions may be set up for use in a wide variety of local autonomous process applications.
