Detailed Description – Allen‑Bradley 700 Series Safety Relays

1. Series Overview – Engineered for Safety Circuits

The Allen‑Bradley 700 series safety relays are specifically designed for machine safety applications requiring reliable, fail‑safe operation. These relays feature mechanically linked (forced‑guided) contacts per IEC 60947‑5‑1 (and EN 50205 Type B for 700‑HP), ensuring that when a contact welds, the relay cannot inadvertently signal a safe condition . The red cover provides quick visual identification of safety devices in the control panel .

Key Family Features:

• ✓ Mechanically linked contacts – all contacts move together, preventing unsafe conditions if a contact welds 

• ✓ Wide contact configurations – 2 to 12 poles, mix of N.O. and N.C. available 

• ✓ Multiple mounting options – DIN rail, panel mount, and PCB pin style 

• ✓ High voltage/current ratings – up to 690V AC, 10‑16A (700S‑CF) 

• ✓ AC and DC coil options – flexible control voltage selection 

• ✓ Bifurcated/gold‑plated contacts – ideal for low‑level switching and low‑energy feedback circuits 

2. 700S‑CF Series – IEC Safety Control Relays

The 700S‑CF relays are the primary IEC‑rated safety control relay series. They provide mechanically linked contact performance required in safety feedback circuits . The red cover and IEC mechanically linked contact symbol on the front ensure easy identification .

Key Specifications:

• ✓ Poles: 8‑pole variants common (e.g., 6 N.O. / 2 N.C., 4 N.O. / 4 N.C.) 

• ✓ Contact rating: 10A continuous; up to 16A thermal (Ith) 

• ✓ Voltage: Up to 690V AC 

• ✓ Coil voltage: AC and DC options available 

• ✓ Mechanical life: 12.5–20 million operations 

• ✓ Mounting: DIN rail or panel screw mount 

• ✓ Bifurcated contact option: Gold‑plated bifurcated version (700S‑CFB) for low‑energy feedback circuits where high contact reliability is critical 

Example Models:

• 700S‑CF620DC – 8‑pole, 6 N.O. / 2 N.C., 120V 60Hz 

• 700S‑CF440DC – 8‑pole, 4 N.O. / 4 N.C., 120V 60Hz 

• 700S‑CFB620EJC – 8‑pole, bifurcated contacts, 24V DC 

• 700S‑CF530DC – 8‑pole, 5 N.O. / 3 N.C. 

3. 700‑HPS Series – PCB Pin Style Safety Relays

The 700‑HPS series provides safety relay functionality in a compact PCB‑pin package, designed for printed circuit board integration. These relays feature mechanically linked contacts per EN 50205 (Type B), making them suitable for safety circuits where PCB integration is required .

Key Specifications:

• ✓ Poles: 2‑pole DPDT (Double‑Pole, Double‑Throw) 

• ✓ Contact rating: 8A, 250V AC 

• ✓ Coil voltage: 6V DC to 125V DC 

• ✓ Contact materials: Silver‑nickel (AgNi) or gold‑plated AgNi for low‑level switching 

• ✓ Red cover for quick safety circuit identification 

• ✓ Wiring diagram printed on top faceplate 

Example Models:

• 700‑HPSXZ24 – 24V DC coil, DPDT, 8A 

• 700‑HPSXZ48 – 48V DC coil, DPDT, 8A 

• 700‑HPS2Z01 – 125V DC coil, DPDT, 8A 

4. 700S‑P & 700S‑DCP – NEMA Safety Relays

These NEMA‑rated safety relays provide robust performance for high‑current applications. The 700S‑P series (10A) and 700S‑DCP series (10A base, 20A master control) are designed for use in demanding industrial environments requiring NEMA A600/P600 ratings .

Key Specifications:

• ✓ Contact rating: 10A (700S‑P), 20A master (700S‑DCP) 

• ✓ NEMA rating: A600/P600 

• ✓ Poles: 4‑8+ configurations available 

• ✓ Coil: 24V DC or AC options 

• ✓ Mounting: DIN rail or open‑type relay mount 

Example Models:

• 700S‑P620A1 – 8‑pole, 6 N.O. / 2 N.C., 10A 

• 700S‑P440A1 – 4 N.O. / 4 N.C., 10A 

• 700S‑DCP620Z24 – 8‑pole, 6 N.O. / 2 N.C., 24V DC 

• 700S‑PK620A1 – 8‑pole master control, 20A
