RATINGS:
The device is supplied by a NEC Class 2 Power Supply supplying:
6 V dc to 14 V dc at 600 mA @ 57.6 KBAUD max.
6 V dc to 18 V dc at 600 mA @ 19.2 KBAUD max.
Conditions of Acceptability – When installed in the end use equipment, the following
considerations are to be examined:
1. The transceivers shall be mounted within an enclosure which is suitable for the intended
application. The enclosure shall also have provisions for Division 2 wiring methods as
specified in the National Electrical Code or Canadian Electrical Code, as applicable.
2. The transceivers must be used within their Recognized “Ratings” at an acceptable
transmission rate. “Increasing the baud rate may impair the safety characteristics for
Class I, Division 2 Hazardous Locations.”
3. Installations and use should be in accordance with the National Electrical Code or
Canadian Electrical Code, as applicable.
4. The connectors shall not be connected or disconnected while circuit is alive unless area
is known to be nonhazardous.
5. The end product shall be marked with a warning for the end user indicating that changes
to the baud rate may impair the safety characteristics for Class I, Division 2 Hazardous
Locations.
Input voltages for Model# DGRO9RFS are determined by the label on the bottom of the board. If
the board has Label A shown below the input voltage is 6 to 14 volts DC.
If the board has Label B shown below the input voltage is 6 to 14 volts DC at a
maximum baud rate of 57.6 KBaud or 6 to 18 volts DC at a maximum baud rate of
19.2 KBaud, operation mode of multipoint slave or multipoint slave/repeater only.
