8 A

Rated output current: 0.2 A per point, 3.2 A per common

Residual voltage: ≤ 1.2 V

Leakage current:

With wire breakdown detection: ≤ 0.7 mA

Without wire breakdown detection: ≤ 0.1 mA

ON delay: ≤ 0.2 msec.

OFF delay: ≤ 0.5 msec.

Overload current protection function: Turns OFF the outputs

when overcurrent is detected

Overheat protection function: Turns OFF the outputs when

overheat is detected

Diagnostic function: When the overcurrent, overheat and

open load (disconnection) are detected, notifies to the

status bit of upper input area. Refer to the users manual for

details

Note: Status is disabled with option code: /D1 (without wire

breakdown detection).

(When driving an inductive load, connect a diode in parallel

with the load.)

INSTALLATION

Operating humidity: 30 to 90 %RH (non-condensing)

Atmosphere: No corrosive gas or heavy dust

Mounting: Surface or DIN rail (35 mm rail)

Weight: 180 g (0.40 lb)

PERFORMANCE

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 1500 V AC @ 1 minute

(output or sensor excitaion toEtherCAT or FE to power)

STANDARDS & APPROVALS

EU conformity:

EMC Directive

EMI EN 61000-6-4

EMS EN 61000-6-2

RoHS Directive

EN 50581

FUNCTIONS

■ WIRE BREAKDOWN DETECTION

The function to notifies to the status bit of upper input area

in case of open load (disconnection) of discrete output is

detected.

Connect output load under 10 kΩ.

Pull-down resister is mounted to detect disconnection so

weak leakage current flows even when the output is OFF.

Status bit is disabled and pull-down resister is not mounted

with option code: /D1 (withourt wire breakdown detection).

PC CONFIGURATOR

The following parameters can be set with using PC

Configurator Software (model: R7CFG)

Refer to the users manual for the R7CFG for detailed

operation of the software program.
