Wireless Interface RAD-ISM-900-SET-UD-ANT One-way (point-to-point) Monitoring or Control User Manual ) ) ) Figure 1. RAD-ISM-900-SET-UD-ANT Notice: These devices must be wired in accordance with Class I, Div. 2 wiring methods as described in the National Electric Code, Article 501-4(b) or the authority having jurisdiction.Transmitter unit is to be used with a purely resistive antenna when installed in Class I, Div. 2 areas.
The RAD-ISM-900-SET-UD-ANT is a Frequency Hopping Spread Spectrum radio designed for the professional installation and integration with other products. When installed with an approved antenna and cable, the system integrator needs to make sure that the unit’s FCC label, or a copy of the FCC label, is clearly visible on the outside of the integrated product. The RAD-ISM-900-SET-UD-ANT is approved within the 902 to 928 MHz ISM Band under Part 15 of the FCC Rules and Regulations.
RAD-ISM-900-UD Transmitter 4-20mA Current Loop with 2-Wire Device Note: Incorrect antenna placement and positioning can have a significant impact on the performance of the RAD-ISM-900-SET-UD-ANT. Keep the Omni antenna vertical and mounted as high as possible. Extra cable may be required to achieve Line-of-Sight (LOS) between the Transmitter and the Receiver. For applications that require the antenna to be mounted away from the Transmitter, please contact your distributor for cable and antenna options.

RAD-ISM-900-UD Receiver Block Diagram Receiver Indicator LEDs RF LED - Flashes once every two seconds when transmitter is OFF or out of range. - Flashes rapidly when signal strength is marginal. - Solid green when a secure link is established. LEDs 1 & 2 - Show status of discrete inputs 1 & 2. Solid green = ON. RF Link: Internal dry contact Form C relay. May be wired as Normally Open (NO) or Normally Closed (NC).

Note: The RAD-ISM-900-UD Receiver Analog Output is a 3-wire device and should be wired to the RTU/PLC just as you would a normal 3-wire current loop device.This wiring configuration is for the Receiver only and must be followed regardless of the type of current loop device on the Transmitter side of the loop (i.e., 2-wire, 3-wire, or 4-wire). Example A RF Link contact is wired to a warning light using the (NC) contact.
Analog (4-20mA) Wiring Likewise, if the Analog signal is required to drop to zero (0 current) when RF Link is lost, it can be wired in series to the RF Link Output in this fashion. Note: Either the discrete Outputs or the Analog can be wired through the RF Link contacts but not both. Maximum OFF voltage for the discrete input is 60VAC. Use of a 2Watt 10k ohm resistor at 110VAC in parallel across the input will help ensure minimum and maximum ON and OFF states.
