127 Converts between physical I/O and CAN (J1939) data link commands System throughput: All channels are scanned in 100 ms Low-Level input voltage range: 0 to 0.8 V High-Level input voltage range: 3.75 to 24V Inputs have internal pull-up resistors LED to indicate communication network status Compact size (see mechanical drawing, FIGURE 65)
DISCRETE I/O SPECIFICATIONS ELECTRICAL SPECIFICATIONS Accept 5-32 V DC power (12 or 24V DC nominal) Over voltage capability is 32 V DC for 1 hour @ 85°C Resistive Loads rated for 3A@30 V DC Normally Closed (NC) relay contacts rated for 3A@125 V AC / 2A@277 V AC / 3A@30 V DC Normally Open (NO) relay contacts rated for 5A@125 V AC / 2A@277 V AC / 5A@30 V DC Inductive Loads rated for 0.5A@250 V AC cosφ=0.4 Maximum current draw of 400mA + 50mA per energized relay @ 12V DC Power supply inputs are protected against transient surges and short circuits and are isolated from I/O Isolation voltage: 4000 V AC (rms), 50/60 Hz for 1 min. between coil and contacts, 750 V AC, 50/60 Hz for 1 min. between contacts of the same polarity ENVIRONMENTAL SPECIFICATIONS Encapsulated in a rugged aluminum housing with watertight Deutsch connectors (IP65 rating) Operating temperature range -40 to 85°C (-40 to 185°F) The ambient storage temperature range is -50°C to +120°C. It is protected against 95% humidity non-condensing, 30°C to 60°C. Designed to meet relevant European standards for EMI/RFI/Immunity without the use of external filtering (Third party testing is being pursued). NETWORK COMMUNICATIONS INTERFACE Incorporates an SAE J1939 communications port with variable slew rate on the transceiver to accommodate different CAN (SAE J1939) connections (capable of working on both the EMCP 3 GSC Primary and Accessory J1939 data links) Node address is auto configurable as per J1939-81
