Compact IO Module AO-8-C

• Screwless installation with click-on DIN-rail communication bus and power connectors
• Push-in spring connectors for cables
• Individually detachable terminal blocks per channel

The 8-channel analogue output module generates voltage control signals. Its 8 individually configurable channels are short-circuit protected, can deliver precise voltages from 0 to 10 V, and have programmable safeguard values in case of a communication failure from a serial Modbus controller.

T Bus connecter (Terminal C) required for MODBUS + and – connection, along with other supply voltage 24VDC, and consumes 15mA.
If more than 1 module is being installed, you only need one terminal connector. If connecting, say, 10 of the same or different modules, only one T Bus connector is required.

Communication: Modbus RTU (RS485) at speeds up to 57600 bps. Use no parity, 8 data bits and 1 stop bit. The module will automatically detect the bus communication speed (9600, 19200, 38400, or 57600 bps).
Modbus address: The address of the module can be set from 1 to 63 by changing the position of dip-switches 1-6. Each dip switch represents a binary value, as indicated on the module and the datasheet.
Modbus loop termination: On the last module, the Modbus loop must be closed by connecting a 120 Ω resistor between the A and B sides of the RS-485 loop.

AO-8-C Fidelix Analogue in module

AO-8-C
– Analogue out module
– 8 analogue outputs
– Programmable default status in case of communication failure
– Short-circuit protected outputs
– Pluggable connection terminals
– RS-485 communication with Modbus protocol
– Mounting on DIN rail

The AO-8-C module generates regulating voltage signals.
Each channel can be individually configured to generate 0-10V and is short-circuit protected. In the event of a loss of communication between the module and the sub-central, the outputs assume the predefined status.
Quick and easy installation, with power supply and communication integrated into the DIN rail.
