IP445A
Isolated Digital Output
IP445A modules provide 32 isolated solid-state
relay outputs to safely control discrete devices.
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.
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.
