DK-31BA

Description

DK-31BA is a kit with two relays and IQRF wireless communication. It is primarily intended for development but it can also serve as a final device for some applications.

The user can realize specific functionality by software for internal TR module.

Relays can be controlled via RF e.g. using programmable IQRF remote controller RC-03. Demo software for this configuration is available. Network applications can be developed using the DK-RC-03 development kit.

Hardware

Power supply

DK-31BA is supplied from external power source via the clamp connector J1. The supply voltage is internally converted to 5 V. It is available on the J3 connector. Jumper on the J2 connector should be in the 5 V position (affects the SDI I/O pin only).

Relays

Ultra miniature slim type relays, 150 V, 1 A.

LEDs

LEDs indicate states of the relays (LED on if the NO contact connected).

TR module

Wireless IQRF transceiver module TR-31B or higher, in SIM card format. User program should be uploaded using some of standard IQRF programmers (e.g. CK-USB-02), either wireless or in the programmer.

I/Os and Configuration inputs

CFG1, CFG2 and CFG3 pins can be used as standard I/Os or configuration inputs (via jumpers). The functionality fully depends on user software.

Pin SDI on the J4 connector is a standard I/O.
