Information About 1734-OB8E

The 1734-OB8E is a POINT I/O module which features Eight (8) electronically, protected discrete input channels. This module is manufactured by Allen-Bradley that is primarily used for implementing distributed I/O architecture.

The 1734 POINT I/O product bulletin are compact, low-density I/O modules with compact and space saving design. These are cost-effective modules that requires minimum panel space and supports standard DIN rail mounting. Specifically, the 1734-OB8E is compatible with all POINT I/O communication adapters and Allen-Bradley controller platforms, specifically, the Logix product family, whether CompactLogix and ControlLogix controllers. Output channels of the 1734-OB8E is energized via the control command sent by the master controller over a specific industrial protocol.

The 1734-OB8E discrete input channels comes with a single group of discrete output channels. It has a sourcing output range of 10-28.8 VDC with output current rating of 1.0 A per output, and 2.0 A per module. It has a Surge current rating of 2 A for 10 ms, repeatable every 3 s. It has 8 yellow – output status; 8 red – output fault indicators and 2 green/red – module/network status indicators. Appropriate terminal bases for use with this module are 1734-TB or 1734-TBS wiring base assembly.

The 1734-OB8E requires a POINTBus current of 75 mA @ 5V DC to operate. It has a power dissipation of 2.0 W and power dissipation of 6.8 BTU/hr with isolation voltage of 50V (continuous), reinforced insulation type Tested @ 2500V DC for 60 s, field-side to system. This module requires an external supply voltage to operate, designed for a nominal voltage supply of 24VDC.

The 1734-OB8E has dimensions of 56.0 x 12.0 x 75.5 millimeters and an EFT/B immunity rating of ±4 kV at 2.5 kHz on signal ports. It has an ESD immunity rating of 6 kV contact discharges and 8 kV air discharges. The module has 8 yellow output status indicator lights, 8 red output fault indicators, and 2 green/red module and network statuses. The Allen-Bradley 1734-OB8E's isolation voltage is 50 Volts continuous, tested to withstand 2500 Volts DC for 60 seconds. The module’s keyswitch position is 1 and weighs 35.4 grams. It also has an off-leakage at a maximum of 0.5mA and off-state voltage 28.8 Volts DC maximum. It has an on-state current of 1.0 mA minimum per channel with an on-state voltage drop of 0.2 Volts DC maximum. The operational temperature ranges from -20 to 55 degrees Celsius.

The 1734-OB8E has an output rating of 2.0 Amps per output, not exceeding 4.0 Amps per module. The point-bus current is 75 mA maximum at 5 Volts DC and an output signal delay time for off to on and on to off situations which is 0.1 milliseconds maximum. The 1734-OB8E's power dissipation is 2.0 Watts maximum at 28.8 Volts DC. The model's radiated RF immunity is 10 V/m with 200 Hertz 50% pulse 100% AM at 1890 MHz, 10 V/m with 200 Hertz 50% pulse 100% AM at 900 MHz, 10 V/m with 1 kHz sine-wave 80% AM from 30 MHz to 2000 MHz. It has a relative humidity range of 5 to 95%, non-condensing. Its operating shock is 30 G and its non-operating shock is 50 G. The 1734-OB8E’s storage temperature range is between -40 and 85 degrees Celsius and it can supply a current of 32 mA. The current transient immunity is ±1 kV line-line (DM) and ±2 kV line-earth (CM) on signal ports, and the thermal dissipation is 6.8 BTU/hour maximum at 28.8 Volts DC.
