Product Introduction

1MRS050641E BIO1 is a Digital I/O board, mainly used in ABB's Machine Terminals. When using the ABB 500 series I/O architecture or for certain protection devices, PLC/DCS systems, the BIO1 module can be used as a field I/O expansion, working together with the coupler or communication base.

Product Details

The signalling relay outputs (BIO1 1MRS050641E) are not heavy-duty outputs,s and thus they cannot be used for controlling, for example, a circuit breaker. Available relay contacts are either Normally Open or Normally Open/Normally Closed type (NO or NO/NC).

Digital I/O boards：

BIO1: threshold voltage 155 V DC

BIO1: threshold voltage 80 V DC

BIO1: threshold voltage 18 V DC

The main working principle of the I/O expansion module is as follows:

1. Sampling digital input status
The input annels inside the module are connected to on-site switch quantity signals. The received levels (such as 24 V DC switch quantity) are converted into digital logic signals and sent to the main controller through the backplane bus.
2. Output drive control for execution equipment
When the control host determines, es based on logical judgment, that it needs to drive a certain output line, it will send instructions through the I/O bus to the module. The module then outputs control levels to the designated output channels to drive external relays, indicator lights, etc.
3. Isolation and Protection
The module itself features electrical isolation and protection design, which ensures that the on-site signals are isolated from the control system logic, thereby avoiding electrical interference and short-circuit risks.
4. Communication with the main system
Communicate with the control system via the I/O backplane or coupler, update input signals in real time, and transmit output commands.

REM 543 and REM 545

BIO1 1MRS050641E is used for REM 543 and REM 545.

The REM 543 and REM 545 machine terminals differ from each other regarding the number of digital inputs available.

The digital inputs of the REM 54_ machine terminals are voltage-controlled and optically isolated. For technical data on the digital inputs.

The parameters for input filtering, input inversion, and pulse counters can be set in the Configuration menu under each I/O card (e.g., Configuration/BIO1 1MRS050641/Input filtering).
