Description

The Modbus module in an IP65 housing with 4 digital inputs was developed for decentralized switching tasks. It is suitable for detecting potential-free switch states from electrical limit switches and their external status display such as fire dampers or vent valves. The inputs can be operated by means of potential-free switches or contacts or used as voltage inputs. The inputs can be scanned by means of standard registers via a Modbus master. Module address, bit rate and parity are set with two rotary switches or by software.

FAQ's

What can I do if the red ERROR LED on the module lights up or there is no communication?

There are several possible causes, please check the following:

- Operating voltage (A1 / A2) connected and sufficient for the device.
- BUS (A- / B+) connected and not reversed. Pay attention to (- / +), not to A/B.
- Address (rotary switch) set correctly, must not occur twice or be 0.
- Bit rate and parity (rotary switch) set correctly, only possible in programming mode (see mounting note).
- Shielded and twisted cable used.
- Termination resistor (120 Ω) set on both sides.
- Bias resistors available once on the BUS.
- Timeout high enough for all participants to respond (approx. 10 ms).
