Product Description:
B&R Automation created the MDA163-0 Digital output module for use in industrial automation systems. The output module has sixteen relay outputs, which are separated into four groups, each with its own reference potential.
The maximum switching voltage that the MDA163-0 digital output module can handle is 24 VDC, and it can handle up to 30 VDC. In addition, it can handle switching voltages up to 250 VAC, which is equivalent to 220 VAC. Each output has a maximum current of 2A, whereas each group has a maximum of 5A. The switching time for logical 0 to 1 and logical 1 to 0 transitions is around 10 and 15 milliseconds, respectively. The mechanical switching life of the module surpasses twenty million operations, while the electrical switching life surpasses one hundred thousand operations. When output 1 is turned on, 4.2 W of power is consumed at +15 V. When we switch from output 0 to 1, the power drain increases to 10.3 W. In contrast, when output 0 is active, the consumption at +15 V is zero W. The output module consumes 0.2 W at +8 V. Each relay output has an accompanying LED indication that shows the current condition of that output in real time. Proper operation necessitates the use of external protection circuits. There is a dielectric constant of 2000 V_eff between the coil and the contact.
To help in signal isolation, MDA163-0 digital output module incorporates a distinct reference potential for each of its four groups. Relays have a set, non-configurable number of outputs and groups of outputs. The module can be used with power sources that provide either +8 V or +15 V. It allows load control within specified voltage and current restrictions and combines well with other components in automation cabinets.
Frequently Asked Questions about MDA163-0:
Q: Does the MDA163-0 require external protective circuits for safe operation?
A: Yes, external protective circuits are required that safeguard the module against voltage spikes and overcurrent conditions during switching.
Q: Why is the switching delay of MDA163-0 set at around 10–15 milliseconds?
A: The delay supports controlled switching transitions that minimize contact wear and enhance electrical switching life and reliability.
Q: How does MDA163-0 manage high-load AC switching up to 250 VAC?
A: It uses relay-based outputs that are rated for AC switching, ensuring support for 220 VAC with a 250 VAC maximum limit.
Q: Do the relay outputs of MDA163-0 support continuous 2 A current per output?
A: Yes, each relay output handles up to 2 A of current, which allows switching of moderate AC or DC loads efficiently.
Q: Why does MDA163-0 have different power consumption levels at different states?
A: Power varies based on output status; it draws 10.3 W during transitions and 0 W when output 0 is active, optimizing energy usage.
