The modules are 4 channel analog or relay, and multiple modules can be stacked on a DIN rail as a mixture of analog and digital signals, all linked on an RS485 bus to ONE RX receiver.
The modules can alternately be added to a full DAQ system where some of the data [which is normally for Quality Assurance] may be needed for control or display by the plant operations group
The Hanwell 434MHz network has a range up to 3km and good performance in buildings and even from within enclosures.
Almost any measured variable input to remote battery powered data logging [100000values] radio transmitters
Multiples of 4ch outputs available at the receiving station as analog or relay signals
One RX receiver only required for many MS1000 modules.
Industrially hard product performance - REPLACE WIRING FOR DIFFICULT INSTALLATIONS
Use for emergency repairs to bypass wiring on a critical plant control loop on breakdown - fast and easy.
cost under $350 per loop in a 20 channel system
