Wireless 4-20 mA mulitiplexer

Port Coguitlam, B.C., Canada—Using frequency hopping spread spectrum, HOPLink modules allow 4 analog and 7 digital channels, with 12-bit resolution, and CRC-16 error detection to be transmitted up to 2 miles line-of-sight using Omni antennas, further with high gain directional antennas. Communication through steel or concrete is possible, with reduced range.

Communication through steel or concrete is possible, with reduced range. Frequency hopping spread spectrum is used by the military because of its reliability and security. Frequency hopping patterns are user configured to allow multiple devices to operate in the same area. Omnex Control Systems Inc.
