More Information

Overview Manuals Signal Modes Output Channels Field Connection Application
  • Supports plus or minus 10 V output mode
  • Provides two analog output channels
  • Requires one separately ordered TB712 terminal block

7AO352.70 is a two-channel 12-bit analog output screw-in module configurable for plus or minus 10 V or 0 to 20 mA signals.

It generates analog setpoints for compatible drives, valves and process devices from a System 2003 CPU.

Before installation or replacement, verify the selected voltage or current mode, load impedance, channel common and polarity, TB712 terminal block, cable shielding, project scaling and safe fallback value.

Availability, condition, price, and shipping time for 7AO352.70 are confirmed during quotation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can B&R 7AO352.70 mix voltage and current outputs?
Yes. Each channel can be selected independently for ±10 V voltage output or 0 to 20 mA current output using its hardware switch. Confirm both switch positions, software scaling, terminal wiring and connected-load requirements before commissioning.
Is the TB712 terminal block included with B&R 7AO352.70?
No. B&R says one TB712 must be ordered separately; verify the screw-clamp or cage-clamp version and terminal condition.
Why can a 0 to 20 mA loop from B&R 7AO352.70 stay at zero?
Check channel mode and scaling, loop continuity and load impedance, terminal assignment, common and polarity, forcing status and whether the application is writing the channel.
What should be checked before connecting a drive to B&R 7AO352.70?
Verify whether the drive expects plus or minus 10 V or current, its input impedance, common reference, shield termination, scaling, direction and safe zero behavior.
What should be verified about B&R 7AO352.70 outputs when the host CPU stops or reports a fault?
Verify the actual output behavior required by the machine project and test it under controlled stop and fault conditions. Do not rely on the analog module alone as a safety function; use an appropriate external safety or shutdown circuit where the actuator must always reach a defined safe state.
What should be backed up before replacing B&R 7AO352.70?
Save both channel modes, scaling, limits, zero and span adjustments, fallback values, forcing status and the related actuator or drive parameters.
What acceptance tests matter after installing B&R 7AO352.70?
Measure each output at zero, midscale and full-scale command, verify polarity and loop current under load, then confirm safe behavior on stop and fault.
