MR-TP Modbus RTU
Description
The Modbus three-point module with 6 digital inputs, 2 two-level relay outputs and 2 digital outputs was developed for decentralized switching tasks. It is suitable for switching, for example, multi-level pumps and fans or louvers. In this case it is necessary to protect the relay contacts by appropriate load-dependent measures. The inputs and outputs can be switched and scanned by means of standard registers via a Modbus master. The input terminals 1 to 6 are wired with the C2 terminals on two poles to potential-free switches or contacts. The module has a manual control for the outputs. Module address, bit rate and parity are set with two rotary switches on the front or by software. Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.

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).
