Product Description:

B & R Automation is an Austrian based automation technology company known for precision engineered control systems. They design and produce a wide range of industrial automation products, including PLCs, I/O modules and HMIs. Their solutions serve various sectors such as manufacturing, packaging and energy.

The HCMC02-2HS is a compact plug in expansion module for industrial rack systems. It integrates seamlessly with PLC chassis using high density edge connectors. It is designed for DIN-rail or rack slot mounting and supports passive cooling. It includes dual DB9 female serial ports for RS-232 or RS-485 communication. This unit is built with a multilayer PCB and partial EMI shielding on the metal front panel. The LEDs on the panel provide clear status indications including RX, TX, EX, HO, BM and LL. The module is equipped with a rotary switch for NODE NO setting and a tactile RES switch for resets. The device operates on 5 V DC supplied directly through the backplane. The power consumption typically ranges from 2 to 5 watts depending on operating load. The communication interfaces of the model include two serial ports supporting both RS-232 and RS-485 standards. The supported baud rates range from 300 to 115200 bps that meets standard serial communication needs. The galvanic isolation is provided between the communication and system circuits.

The I/O signal lines of the HCMC02-2HS expansion module are optically or transformer isolated. The module interfaces with the main control system using a high speed parallel bus or a proprietary serial bus depending on system configuration. The board construction includes both through hole and surface mount components for mechanical stability and performance. This model is well suited for applications requiring serial communication with isolated and reliable data transfer in compact rack systems.
