MBH88 - 8 x 16A modbus relay

Devantech

Overview

MBH88
Relays 8 VFC with snubbers on N/O
Digital opto isolated inputs 8
Power Universal input: 90 – 264Vac, 47-63Hz
Control interface Modbus RTU over RS485
Relay current Up to 16Amp @24vdc or 250vac
Connections Screw Terminals for N/O N/C and Common contacts

The MBH88 is supplied in a DIN rail mounting case, and provides eight optically isolated inputs and eight volt free contact relay outputs with a current rating of up to 16Amp each. Eight isolated inputs may be used as volt free inputs (ie. direct connection to switches or sensor contacts) or as voltage inputs (5-24vdc).

The module is mains powered via an on-board isolated universal power unit. Control is by a MODBUS RTU RS485 interface with even Parity or No Parity, baud rates of 9600, 19200, 38400 or 115200, and an address range of 0 to 127, selectable by dip switch. The full MODBUS specification is here.

All relays have snubber circuits across the normally open contacts and are suitable for inductive loads such as motors, solenoids etc.

Relay power rating

If the contact load voltage and current of the relay are in the region enclosed by the solid and dotted lines in the figure below, the relay can perform stable switching operation. If the relay is used at a voltage or current exceeding this region, the life of the contacts may be significantly shortened.
