DB-24SSR/DIN 24-ch AC Solid-State Relay Board, DIN-rail Mount

DB-24SSR/D/DIN is a 24-channel solid-state relay board for switching AC loads from low-level control signals. Each channel is a Form A (normally open) solid-state relay rated at 4 A @ 240 VAC, and it is energised by a 5 V signal on the matching channel of the 50-pin header or 37-pin D-sub connector.The board is intended for general-purpose relay output duties where a TTL-level output board needs to drive field loads. Its 37-pin D-sub, OPTO-22 compatible and 20-pin connectors give several ways to connect to host hardware, and screw terminals simplify field wiring. A dedicated LED for each relay shows its status at a glance during commissioning and fault finding.This variant is designed for DIN-rail mounting and is supplied with the CA-3710 cable (DB37 male to male, 45°, 1 M). It is rated for an operating temperature of 0 ~ 60°C.ApplicationsOn/off controlEnergy managementTest automationProcess control

The DB-24SSR/D is a 24-channel AC-type solid-state relay board for engineers who need to switch field loads from a host computer while keeping the controller isolated from ground loops and high voltages. Each of the 24 Form A channels is energised by a 5 V logic signal applied through the 50-pin header or the 37-pin D-sub connector, and a dedicated LED lights when its relay is active.The 37-pin D-sub connector accepts TTL-level outputs from compatible output boards, so the board can serve as a general-purpose solid-state relay output stage. It also connects directly to OPTO-22 compatible boards. Screw terminals simplify field wiring, and the relays offer long life with no arcing, no bounce and no switching noise.This variant includes the CA-3710 DB37 male-to-male cable (45º, 1 m). The base DB-24SSR ships with the CA-5015 50-pin flat cable instead, so the bundled cable is the main difference between the two codes.ApplicationsOn/off controlEnergy managementTest automationProcess control

The DB-24SSR provides 24 Form A solid-state relays on a single daughter board. Each relay is switched by a 5 V signal applied to its channel on the 50-pin header or the 37-pin D-sub connector, so it can be driven directly from a logic output without a mechanical contact.Relay outputs are rated at 4 A at 240 VAC. Because the board isolates the host computer from high-voltage loads and removes ground-loop problems, it suits field wiring of switched AC loads. Twenty-four LEDs show the status of each relay, and screw terminals simplify wiring. Since the 37-pin D-sub connector accepts TTL outputs from other boards, the DB-24SSR can also serve as a general-purpose solid-state relay output board.24 Form A (normally open) solid-state relay channelsRated 4 A at 240 VAC, 0.4 A @ +5 V maximum consumptionSupplied with CA-5015 flat cable, 50-pin, 1.5 mDimensions 130 mm x 220 mm x 32 mm (W x L x H)ApplicationsOn/off controlEnergy managementTest automationProcess control

DB-24SSRDC is a DAQ daughter board carrying 24 normally open (Form A) solid-state relays. It isolates field logic signals from the host computer, which removes ground-loop issues and protects the host from damaging voltages. Each relay is energised by a 5 V signal applied to its channel on the 50-pin header or the 37-pin D-sub connector.The DC-type variant is rated at 4 A over 3~50VDC. Twenty-four LEDs show the state of each relay, and screw terminals make field wiring straightforward. Because the board offers a 37-pin D-sub connector, it can be driven from any TTL output board, so it also works as a general-purpose solid-state relay output board.This ordering code includes the CA-5015 flat cable (50-pin, 1.5 m) for connection to a compatible board.ApplicationsOn/off controlEnergy managementTest automationProcess control
