DR-IO Series DIN rail mount input/output modules are ideal for connecting real world discrete signals to a computer interface and other electronic equipment. Most computer interfaces can only sense or generate low level TTL (0/5Vdc) signals. The DR-IO-OAC and DR-IO-ODC output modules can be used to sense high level ac and dc signals. The compact design of the DR-IO modules permit high density mounting on a standard DIN rail. The input modules are available with negative and positive logic versions. Negative logic modules produce a high logic signal when the input signal from the field goes low and a low logic signal when the field input goes high. With the positive logic modules, the logic signal follows the field signal that is, the logic signal is high when the field signal is high and low when the field signal is low.

Low turn on current
I use these as solid state relays with the NI 9403 5V TTL DIO module. The problem I have always had is that the module only outputs 2mA per channel. These DR-IO modules let me go directly from the TTL signal to a 3A 208V powered device. If I need more than that I can used them to turn on a larger relay. The internal fuse make them a great space saver too.

output charge leak without control signal
These modules leak a low level charge without no control signal applied.
This is not noticeable with mechanical relays due to the low impedance which allows the charge to bleed without enabling the relay. However, with a sold state device with an high impedance will see a voltage on the input without a control signal applied.

Hello, could you please tell me what the propagation delay of the OAC and ODC output modules are?
The closest rating I can give you is the max switching speed which is 10khz
