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.

Universal input: 90 - 264Vac, 47 - 63Hz
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.
| load type | Typical applications | Rating | Max DC load capacity

| AC1 | Non inductive or slightly inductive loads |
16A @ 250V AC | |
| AC15 | Control of electromagnetic load (>72VA) |
3A @ 120V AC 1.5A @ 240V AC |
|
| AC3 | Control of motor | 750W | |
| DC1 | Non inductive or slightly inductive loads |
16A @ 24V DC | |
| DC13 | Control of electromagnetic loads |
0.22A @ 120V DC 0.1A @ 250V DC |
