The Allen-Bradley 1734-OX2 Point I/O module is a Two (2) channel Form C Relay Output Module. This module has a 2mA current leakage, load-dependent output voltage of 5-28.8V DC at a 2A resistive load to 240V AC at a 2A resistive load. The 1734-OX2 has an output current rating per power between 2A at 5.28V DC and 2A at 240V AC. It also has a maximum power rating of 250W at 125V AC resistive output to 31VA at 125V DC in inductive output. The 1734-OX2 has a contact resistance of 30milliohms, and a switching frequency of a single operation per 3s at 0.3Hz load rated.

The 1734-OX2 has a maximum Operate/Release time of 10ms, alongside 1.2ms average bounce time. Its minimum load contact is 5mA per point, and the half-life of each electrical contact made is about 1 million cycles (resistive), and 100,000 cycles (inductive). The 1734-OX2 has 3 colored indicators (2 green/red, and 2 yellow) for displaying module/network status, and outputs status, and has it has a 7 key-switch position. The 1734-OX2 is installed on either the 1734-TB or -TBS wiring base assembly. Its POINT BUS current is 100mA at 5V DC, and its power dissipation is 0.5W, with 1.7 BTU/hr (max) thermal dissipation. It has an isolation voltage of 250V tested at 2500V DC for 1s between 2 sets of contacts. It has shipping dimensions of 2.21in x 0.47in x 2.97in and a weight of 1.15oz. The 1734-OX2 has an ambient temperature between -4 and 131 deg. Fahrenheit, at an IEC 60068-2-30-tested 5-95% non-condensing relative humidity.

The 1734-OX2 is a relay output module with Form C contacts. This module is compatible with 5VDC/24VDC and 110 VAC / 220VAC voltages or any voltages in between the provided range. It is ideal for use in applications where electrical loads have different voltage ratings, eliminating the need of installing interposing relays.

This module is an Allen-Bradley output module that belongs to the POINT IO product family used for implementing distributed IO applications. POINT IO product family are compact, low density modules popular for its cost-effectiveness and ruggedness. It may be used with CompactLogix and ControLlogix controller platform.

Each output channel has a single common terminal, Terminals 4 for Channel 0 and Terminal 5 for Channel 1. The Normally Open (N.O) connection is established across terminals 4 and 0 while Normally Closed (N.C.) connections is across terminals 4 and 0 for Channel 1. For Channel 1, N.O. is across terminals 5 and 3 while N.C is across terminals 5 and 1. Compatible supply voltages may be from +5V dc to 240V ac, depending on relay load. 12V, 24V dc, 120V, 240V ac power for the module is provided by the internal power bus.

This module has Module Status and Network Status indicators and output channel LED indicators to indicate output channel activity. Output fusing is not included with the module. External fusing may be applied accordingly with this module ideally with the use of a Fuse type terminal block. Compatible wiring base assembly for this module is 1734-TB or 1734-TBS while keyswitch position is no.7.
