Technical Specifications

Isolated Digital Inputs

Number

4

Features

Active high, programmable, overvoltage-protected.

Range:

4 mA, 24 VDC

Sample time:

1.0ms; the regulator is updated if the input stays in
the same state for 3.0 ms.

Supply:

24 VDC (short circuit protected) is available from
the RMI board. This supply must not be used for
powering external circuits.

Isolated Analog Input

Number:

1

Features:

10-bit resolution, overvoltage-protected,
programmable, software-calibrated.

Range:

0 to 10 VDC (jumper setting: V IN)
0(4) to 20 mA (jumper setting: C IN)

Sample time:

1.0 ms

Moving average:

4 scans

Isolated Frequency Input

Number:

1

Features:

Software-scaled.

Range:

0 to 200 kHz, 15 VDC

Input Impedance:

2.64 k

, 2.2 nF

Sample time:

5.0 to 20.0 ms in steps of 1.0 ms, or 20.0 to
500.0 ms in steps of 20.0 ms

If sample time

20.0 ms, scan time = 1.0 ms and

moving average = scan time.

Otherwise, scan time = sample time / 20, and
moving average = sample time / 20
