+86 1535940827516-Point DC Output Module · CL Chassis I/O Platform
1756-OB16E is a 16-point source output module with electronic fusing arranged as two groups of eight outputs. It switches 12/24 VDC field loads across a 10 to 31.2 VDC operating range.
The official data specifies 1 A maximum per point, 8 A maximum per module at 60 °C, 3 mA minimum load current and maximum delays of 1 ms in either switching direction.
Engineering checks should cover group loading, inrush current, electronic-fuse behavior, field supply, fault/program state configuration, terminal-block selection, output ownership and the chassis power budget.

1756-OB16E is a 16-point electronically fused source output module for 12/24 VDC field loads, arranged as two groups of eight outputs with separate group loading limits.
1756-OB16E operates from 10 to 31.2 VDC and supports up to 1 A per point and 8 A per module at 60 °C, subject to load and inrush limits.
The electronic fusing in 1756-OB16E protects output groups differently from replaceable mechanical fuses, so fault behavior, reset procedure and configured output states must be reviewed.
1756-OB16E uses compatible 1756-TBNH or 1756-TBSH removable terminal blocks; the installed block, keying and field wiring must match the replacement module.
Before replacing 1756-OB16E, verify field-supply polarity, group current, load inrush, terminal-block wiring, output ownership, fault/program state settings and chassis power capacity.
A 1756-OB16E inquiry should include catalog and series, quantity, field voltage, load type and current, terminal-block catalog, chassis details and clear wiring and nameplate photographs.
Send the complete 1756-OB16E catalog number, revision, quantity, destination and nameplate photo. Identification details will be checked before availability and lead time are confirmed.
