BLASI – ISM-2000/24VDC 2-channel multiplexer
The BLASI ISM-2000/24VDC 2-channel multiplexer controls dual Pantron light barriers for comprehensive safety monitoring in industrial door systems. This DIN-rail mounted amplifier powers and multiplexes two IR-M12 transmitter/receiver pairs, enabling up to 30m detection ranges across TA-series equipment entrances while preventing channel crosstalk. Manual/automatic gain adjustment compensates for dirt accumulation while test functions verify wiring integrity to PLC safety inputs via WAGO terminals. Alarm and error outputs ensure Category 2 compliance with 24VDC operation.
Product Details
The BLASI ISM-2000/24VDC 2-channel multiplexer provides centralized control for dual Pantron through-beam light barrier systems monitoring wide industrial door openings around TA-6/TA-7 equipment. DIN-rail mounted in control panels, this amplifier simultaneously powers two IR-M12 transmitter/receiver pairs through screw terminals or plug connectors, multiplexing 4kHz modulated infrared signals to prevent interference between closely spaced beams protecting personnel from pinch hazards during door closure operations.
Dual operating modes of the 2-channel multiplexer offer manual gain settings for clean environments and automatic power adjustment compensating for lens contamination, misalignment, or degradation common in Dubai’s dusty manufacturing facilities. Sensor control continuously monitors transmitter/receiver health while test button enables diagnostic mode displaying alignment status, wire breaks, and short circuits via multi-color LEDs. Light/dark switching per channel adapts to diverse PLC safety logic requirements.
Two independent switching outputs (60V/100mA PhotoMOS, short-circuit proof) signal beam interruptions to Siemens PLC safety relays through WAGO terminal blocks, with 8ms response time meeting emergency stop requirements. Separate alarm output activates when sensors exceed contamination thresholds while error output indicates internal faults. External test input supports safety circuit validation. Operating from 24VDC (±20%), the ISM-2000 maintains reliable Category 2 performance across -20°C to +60°C, ensuring continuous protection for high-traffic automation environments.
