D2 W SIO wireless modules are economical solutions for monitoring remote process signals and are housed in a weatherproof
(IP66) enclosure. They connect to discrete, pulse, or analog signals from process transducers, and transmit these signal values by radio. Capable of being powered by battery-only supplies, these products are particularly suitable where power is not available.
Applications
Wireless connection of flowmeters or energy meters
Monitoring of storage tanks
Monitoring cathodic protection on pipelines
Wireless alarms from power reticulation fault-relays
Features
Class I, Division 2 hazardous areas approved (USA/Canada) - pending
Input-only transmitter unit, two digital/pulse inputs and one analog input
Networks with multi-I/O and gateway units
Sensor signals, inputs are transmitted to a transceiver module where the signals are re-created as output signals or passed by a gateway device to a host device such as a PLC or SCADA system
Extremely low power consumption by reverting to "sleep" mode
Multiple power supply options including battery-only supply
Weatherproof (IP66) enclosures
Up to 3000 wireless units per network
Inputs on any D2 W SIO can be wirelessly linked to an output on any unit. Inputs can be linked to multiple outputs.
Up to 5 intermediate transceiver or gateway units can be configured to link inputs or outputs to transmitters or receivers
Interface with Modbus via the gateway device
External inputs plus internally calculated values, analog set-point status, pulse rate and pulse total, power supply voltage, power supply alarm
Set-point status generated by comparing analog input to high and low set-points
Pulse inputs generate a separate pulse count value and a pulse rate value. Pulse rates are treated as internal analog registers with a configurable maximum value.
Power supply generates internal signal which can be transmitted as low normal supply voltage status, low battery voltage status, and battery voltage (analog)
Can connect to up/down counter transducers such as shaft-encoders
Easily configured to repeat the transmission up to four additional times after the initial transmission to ensure that the transmission is received correctly.
