A major IP445A advantage is its flexibility. The module supports wide range bipolar (AC or DC) voltage switching. Each port can be configured for high or low-side switches. The outputs are TTL-compatible when configured as low-side switches using on-board socketed pull-up resistors.

Isolation protects your computer system from noise, transient signals, and field wiring faults. Outputs are grouped into four 8-channel ports. Ports are isolated via solid-state relays from the logic and from each other.

Readback buffers simplify output status monitoring. And for easy closed-loop monitoring of critical control signals, use the IP445A with an IP440A input module.

Specifications

Digital Outputs: Output channel configuration: 32 isolated solid-state relays support AC or DC (high/low-side switching) operation.

Isolation: Logic and field connections are optically isolated by solid-state relays. Individual ports are also isolated from each other. Output lines of an individual port share a common connection and are not isolated from each other. IP Logic and field lines are isolated from each other for voltages up to 250V AC or 354V DC on a continuous basis (unit will withstand a 1000V AC  dielectric strength test for one minute without breakdown).

Voltage range: 0 to ±60V DC or peak AC.

Output ON current range: 140mA maximum continuous (up to 1A total per port).

Turn on time: IP445A 1mS typical, 2mS maximum. IP445AE 1mS typical, 2.5mS maximum*.

Turn off time: IP445A 1mS typical, 2mS maximum. IP445AE 1mS typical, 2.5mS maximum*.

*maximum values are measured at 85°C

Output pull-up resistors: 4.7K ohms, socketed.

IP Compliance (ANSI/VITA 4)

Meets IP specifications per ANSI/VITA 4-1995.

IP data transfer cycle types supported: Input/output (IOSel*), ID read (IDSel*).

Access times (8MHz clock): 0 wait states (250ns cycle).

Updates: Requires four 8-bit writes to update all channels.

Environmental

Operating temperature: 0 to 70°C (IP445A) or -40 to 85°C (IP445AE model).

Storage temperature: -40 to 150°C (all models).

Relative humidity: 5 to 95% non-condensing.

MTBF: 713,455 hrs at 25°C, MIL-HDBK-217F,Notice 2.

Power: +5V (±5%) all outputs on: 200mA maximum. ±5V (±5%) all outputs off: 8mA maximum.

The IP445A is a drop-in replacement for the IP445, please see the known differences document below for more information.
