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
• Failsafe outputs to predefined state on communications failure
• Bi-colour LED for module status information
• Yellow LED indication per analogue output

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.

Applications

BMS and monitoring.
