Seneca Z-PC Line module: ZC-SG

The ZC-SG module allows to manage the load cell signals and to process the weight value, with
two types of communication: CANopen protocol, ModBUS protocol (RS232 serial).

General characteristics

Hardware

 Sampling frequency settable from 12,53 Hz to 151,71 Hz.
 1500 VAC isolation amongst inputs, power supply and CAN interface.
 Protection against ESD discharge up to 4 kV.
 Adjustable rejection at 50 and 60Hz.
 Strain gauge directly powered by the instrument.
 Ratiometric measurement.
 Simplified power supply and serial bus wiring by means of the bus housed in the DIN rail.
 1 to 64mV/V sensitivity, settable by software for real/integer values.

Software

 Load cell calibration with known weight
 Load cell calibration is not necessary if the load cell sensibility is known.
 Configurable digital I/O.
 Stable weight indication via digital output / Modbus register / PDO
 Remote writing of the tare in volatile and/or non volatile memory through digital input / CAN

commands.

 Led Indications: Power Supply, CAN communication, MODBUS-RTU communication, Inputs

fault.

 Alarm generated when programmable threshold is exceeded.
 Measurement stabilization through a programmable number of samples, ±30000 points

hysteresis activable.

Communication

 CAN Interface with CANopen protocol: up to 1 Mbps speed.
 CANopen Baud rate and Node ID configurability by DIP-switches or software.
 Nodeguarding or heartbeat
 RS232 Serial Communication with MODBUS-RTU protocol
 Complete configurability through specific software downloadable in the website www.seneca.it.

Easy-SETUP

To configure the Seneca Z-PC Line modules, it is possible to use Easy-SETUP software, free­downloadable from the www.seneca.it; the configuration can be performed by RS232 or RS485
bus communication.
