Modbus contact closure sensor TX CONTACT 600-039

LoRaWANLoRawireless

Overview
The TX CONTACT LoRaWAN state change sensor detects and immediately transmits contact state changes (open/closed) from a dry contact or open-collector input. It is designed for building management, equipment monitoring and industrial applications where fast, low-power wireless notification of binary state changes is required.

Key features

• Immediate transmission on state change (open/closed).
• Inputs supported: dry contact and open collector.
• Minimum detectable contact duration: 50 ms.
• Default periodic transmission: 5 minutes (configurable).
• Long-range radio using LoRa technology (typ. >5 km in open terrain).
• Replaceable 3.6 V Type D lithium battery; battery life up to 15 years depending on configuration and environment.
• Enclosure rating IP65 (NEMA 4 equivalent) for indoor/outdoor use.
• Three status LEDs for local diagnostics.
• Designed for BMS integration: compatible with public/private LoRaWAN and Enless LoRa Easy receivers; data mapping to Modbus, BACnet or JSON/HTTP.
• Certifications vary by model: CE, UKCA, LoRaWAN; FCC and ISED for US variant.

Multiple uses

• Monitoring door and cabinet open/close events.
• Machine status and malfunction detection.
• Remote equipment state reporting and control for building management systems (BMS).

Communication modes & integration

• LoRaWAN mode: operates on public or private LoRaWAN networks; supports the LoRaWAN versions indicated for the product and Class A operation.
• LoRa Easy (Enless) mode: transmits to Enless LoRa Easy receivers which forward data to Modbus, BACnet or HTTP/JSON for direct BMS integration.
• Native decoding and mapping options available when used with Enless receivers or gateways (Modbus table / BACnet objects).
