Description
The eBMS/IO range of I/O modules are designed for use as local I/O within motor control cabinets or as remote I/O connected via TCP or RS485 Modbus.
The eBMS/IO 4AOH-3DO module provides 4 independent analogue output channels with hand- auto override switches and setting potentiometers. Each output has a yellow LED. The module also provides 3 independent 250vac/8A rated digital relay output channels each with change over contact configuration.
The IP20 rated module may be plugged together with other modules on standard TS35 DIN rail or direct mounting; the cascadable design allows power and 2- wire RS485 Modbus communications to connect through without any extra wiring.
Modbus address setting is by rotary switches which are easily accessible underneath the top cover. A bi- colour LED indicates the communications status.
CON (RS485 Master Network Interface) or TCP-CON needed to connect modules to an RS485 Master Network Interface or Ethernet Network Interface.
Features
- 4 analogue outputs 0 to 10v dc
- Hand-auto override switches and setting potentiometer on each analogue output
- 3 digital outputs with change over contacts
- DIN rail or direct mounting
- 24v ac or dc power operation
- Supports RS485 2-wire Modbus Open Communication network

Connectivity
The 4AO 3DO module has one 2-wire RS485 port supporting a Modbus communications network connection to the JACE® controller.
Modules can be networked via TCP, RS485 or mixed networking.
Engineering
Can be engineered via any system with a Modbus interface. Palette files available for Tridium AX and N4.
