DB-24POR 24-ch PhotoMOS Relay Board, OPTO-22 Compatible DAQ Daughter Board

DB-24POR/D/DIN is a DAQ daughter board that switches 24 FORM A PhotoMOS relay channels, each optically isolated at 5,000 Vdc. It suits engineers who need a compact, solid-state switching stage that can be wired from screw terminals and driven through an OPTO-22 compatible connector.Each channel has an LED that shows its relay status, which simplifies commissioning and fault checking. The board offers three connectors: an OPTO-22 compatible connector, a 37-pin D-sub and a 20-pin connector. This DIN-rail variant ships with a CA-3710 DB37 male-to-male cable, 45º, 1 M.Relay ratings are 130 mA at 350 VAC, with an operate time of 0.7 ms and a release time of 0.05 ms. The board draws 300 mA at 5 V, measures 213 mm x 132 mm and operates from 0 ~ 60°C, with storage from -20 ~ 70°C and humidity of 5% to 90% non-condensing. It is RoHS and WEEE certified.ApplicationsOn/off controlEnergy managementTest automationProcess control

It operates from 0 to 60°C and is listed as RoHS and WEEE compliant.ApplicationsOn/off controlEnergy managementTest automationProcess control

DB-24POR/DIN is a DAQ daughter board that switches 24 channels through optically isolated PhotoMOS relays. Its OPTO-22 compatible connector allows it to be connected to OPTO-22 compatible wiring, and this DIN-rail mounting variant is fitted for DIN-rail installation.Each channel is a FORM A PhotoMOS relay rated at 130 mA @ 350 VAC, with an operate time of 0.7ms and a release time of 0.05ms. LED indicators show the status of each relay, and screw terminals support field wiring. The board draws 300 mA @ 5 V and provides 5,000Vdc optical isolation.This variant includes a CA-5015 flat cable (50-pin, 1.5 M). The board is RoHS and WEEE certified and is rated for an operating temperature of 0 ~ 60°C.ApplicationsOn/off controlEnergy managementTest automationProcess control

The DB-24P CR is a 24-channel optically isolated digital input daughter board designed to plug into OPTO-22 compatible digital input cards such as the DIO24, DIO48 and DIO144. Each input uses a bi-directional opto-coupler with a current-sensing resistor, so field signals are electrically separated from the host computer. This separation helps protect the computer against large common-mode voltages, ground loops and voltage spikes common in industrial environments.For DC signals, the board accepts levels from TTL up to 24 V, with an ON voltage level of 2.8 V to 24 V (max) and an OFF voltage level of 1 V (max). For AC signals, the AC filter jumper must be shorted. The input then registers a constant logic high when the AC frequency is 1 kHz or above and the voltage is at least 4 Vrms. Response speed is 20us without filter and 2.2ms with filter.The board draws +5 V at 290 mA and measures 213 mm x 132 mm. It operates from 0 to 60°C and is supplied with a CA-5015 flat cable (50-pin, 1.5 M) for connection.ApplicationsOn/off controlEnergy managementTest automationProcess control
