1734-OV4E

The 1734-OV4E Protected Sink Output Module by Allen-Bradley is a 28.8V DC I/O module with four sinking outputs installed on the 1734-TB or the 1734-TBS base assembly with a single key-switch position. It has a BUS current of 75mA at 5V DC with a signal delay of 0.1ms around its outputs. It requires an external DC power supply for its mode power needs. The 1734-OV4E has a maximum ON-state voltage of 28.8V DC which drops 0.7V DC under full load and at a temperature of 55 °C. It is designed with a maximum ON-state current of 1A per channel with 0.5A OFF state leakage and surges at 2A through 10ms, repeatable after 3 seconds. It has 3 different indicator colors that display the module status. The 1734-OV4E has 4 yellow indicators showing output status, 4 red indicators showing output fault, and 2 green/red indicators showing the module and network status. It has a maximum power dissipation of 1.2 W at 28.8V DC with an equivalent thermal dissipation of 4.1 BTU/hr maximum at 28.8V DC. The 1734-OV4E is installed with a DIN rail, and 7 inches-pounds terminal base screws, and is designated with the T4 temperature code. It has an IEC6100-4-2-rated ESD immunity against a 6KVA contact discharge and 8KVA air discharge. The 1734-OV4E has an open-style enclosure, built for an operating temperature range of -20-55 °C (-4-131 °F) and 5-95% relative humidity non-condensing. It measures 2.21 x 0.47 x 2.97 in. in dimension, and weighs approximately 1.17oz. The 1734-OV4E has 4 outputs and an output voltage of 24V DC with an output current of 3 amps/module. This digital DC sinking output module is electronically protected.
