MRR 16

Multiplexer Reed Relay 16 channels

MRR 16 is a peripheral card that belong to the wide family of professional boards for Industrial ABACO® BUS.

MRR 16 is a typical analog multiplexing card based on Reed relays very fast and with very low contact resistance. If it is necessary are moreover available the Reed relays with mercury wetted contacts.

For each analog input lines are used two Normally Open contacts allowing multiplexer of either Voltage or Current signals.

A normalized 10 pins connector allows the connections of many multiplexer cards as other MRR 16 or MSS 16 and RCV 420.

The analog input signals are connected to a proper low profile connector while the single output analog signal is connected to normalized A/D connectors. So the number of analog signals acquired by any grifo® cards as LAD 02, LAD 12, LAD 13, LAD 15, GPC® 188F, GPC® 550, GPC® 150, GPC® 883, etc. can be increased by adding one or more multiplexer cards as MRR 16.

A series of LEDs shows the card status and let the user perform a visual check of the currently selected input channel.

It is really remarkable an original addressing tecnique used on the card, that joins the management of all the multiplexer cards (MRR 16, RCV 420, MSS 16) installed on the BUS, into a single address.

Moreover to avoid any possible conflict on the input channels when a write operation is performed on the mapping address the selected line is selected and the previously selected line is automatically deselected.

• Interface to industrial ABACO® BUS with 8 or 16 bits addressing space.
• Multiplexing section based on Reed relays, provided of 16 input channels and 1 output channel. Each channel has 2 N.O. contacts.
• Output channel available on all the possible normalized A/D ABACO® connectors.
• Visualization LEDs for card status and currently selected channel.
• Single +5 Vdc power supply
