Product questions
Which input signals can the AS04AD-A accept?
The four channels each accept either voltage or current. Supported ranges include 0–10 V, 0–5 V, 1–5 V, ±5 V, ±10 V, 0–20 mA, 4–20 mA and ±20 mA. Match the channel configuration to the signal.
Are the AS04AD-A input channels isolated from each other?
No. The analog and digital circuits are isolated from each other, but the four analog channels are not isolated from one another. Check the system grounding and signal arrangement before selecting the module.
What supply voltage and conversion time does the AS04AD-A require?
The module uses a nominal 24 V DC supply, with an operating supply range of 20.4–28.8 V DC. The manual specifies 2 ms per channel; firmware V1.02.00 or later is described as supporting 1 ms per channel. Verify the module firmware for the intended speed.
How can I confirm the AS04AD-A is right for my controller?
The AS04AD-A is an AS Series analog input module. Before ordering, provide the controller model, equipment serial number, existing module number and firmware version so the intended configuration can be checked.
