Frequently Asked Questions (FAQ)

Q1: What is the primary function of the 07EA90 analog input module?
A1: The module is used to acquire four safety-related analog signals in the range of 4–20 mA and transmit them to the Advant Controller 31-S via the CS31 bus.

Q2: How many 07EA90 modules can be connected to one CS31 system bus?
A2: A maximum of six modules can be connected, occupying addresses EW00.00 to EW05.15.

Q3: What bus transmission time is associated with the 07EA90?
A3: The typical bus transmission time per 07EA90 module is 1050 microseconds.

Q4: Can the 07EA90 be mounted both on DIN rail and by screws?
A4: Yes, the module can be mounted on a DIN rail per DIN EN 50022 or fixed using screws.

Q5: Is the analog signal electrically isolated from the CS31 system bus?
A5: Yes, the analog input signals are electrically isolated from the CS31 bus interface for enhanced safety.

Q6: What is the required voltage supply for the 07EA90?
A6: The module operates on 24 V DC with a tolerance of +20% to -15%.

Q7: Are there special environmental conditions for operating the module?
A7: The operating temperature range is 0 °C to 55 °C, and the module must be used in environments with 5% to 95% non-condensing humidity.

Q8: How is the module protected against external influences like vibration and shock?
A8: The module is built to withstand vibration (up to 0.5 g) and shock (15 g, 11 ms) in compliance with industrial standards.
