    RV-07B

    The RV-07B is a 19” rack which can hold up to 16 Westermo TR-36B modems as well as two PS-20 power supplies.

    The rack is designed to harsh industrial standards in applications where a number of modems are required in the same location. The rack has passed extensive approvals testing by both Westermo and external test houses, showing the rack can operate in environments with a high level of electromagnetic interference.

    TD-23 HV

    The TD-23 is a simple industrial modem designed to allow cost effective and easy multidrop access (max 16 drops) to legacy serial industrial equipment. Any asynchronous word format can be used from either RS-232 or RS-485 protocols.

    Designed with industrial locations in mind the modem can operate in extremes of temperature and electromagnetic field.The complete galvanic separation of all interfaces ensures earth loops and transients do not interfere with communication.
