Product details

The SR3PACK2BD: Cycle time 6 to 90 ms — enough for most logic and simple process control. Relay output response: 10 ms off-to-on, 5 ms on-to-off. Counting frequency up to 1 kHz on discrete inputs. Operating altitude 2000 m. For the wireman: screw terminals accept up to 2.5 mm² solid or 1.5 mm² with ferrule, torque at 0.5 N·m. IP20 on terminal block, IP40 front panel.

Compliance box tick

Standards include IEC 61000-4-2/3/4/5/6/11 level 3, IEC 60068-2-6 Fc and IEC 60068-2-27 Ea, IEC 61000-4-12, IEC 61000-4-11, and pollution degree 2.

Frequently asked questions

What is the closest alternative if I need just the controller?

The pack includes the SR3B261BD base unit. For a bare controller without the cable, order SR3B261BD directly.

Does this pack have a real-time clock?

Yes, a clock is present. Backup time lasts 10 years at 25 °C. Drift spec: 12 min/year over 0-55°C, 6 s/month at 25°C.

Does it check program memory on power-up?

Yes, program memory is checked on each power-up.

What compliance documents are available?

Standards listed include multiple IEC 61000-4 immunity tests at level 3, IEC 60068-2-6/27 vibration/shock. No specific RoHS/UL mention, but the IEC compliance covers EMC for industrial environments.
