Electrical properties | Service life electrical: see diagram Maximum power dissipation for nominal condition: 1.01 W Test voltage (Winding/contact): 2.5 kVrms (50ÃHz, 1Ãmin., winding/contact) Test voltage (Changeover contact/changeover contact): 2 kVrms (50ÃHz, 1Ãmin., changeover contact/changeover contact) Rated insulation voltage: 250 VÃAC Rated surge voltage: 2.5 kV |
Input data | Coil side Nominal input voltage UN: 24 VÃDC Input voltage range: 18.7 VÃDC ... 46.8 VÃDC (20ðC) Drive and function: monostable Drive (polarity): polarized Typical input current at UN: 42 mA Typical response time: 13 ms Typical release time: 14 ms Protective circuit: Freewheeling diode Status display: Yellow LED |
Output data | Switching Contact switching type: 4 changeover contacts Type of switch contact: Single contact Contact material: AgNi, hard gold-plated Note: If the specified maximum values for multi-layer contact relays are exceeded, the gold plating is destroyed. The maximum values of the power contact relay are then valid. This can result in a shorter service life than with a pure power contact. Maximum switching voltage: 30 VÃAC 36 VÃDC Minimum switching voltage: 2 V (At 24 mA) Limiting continuous current: 50 mA Maximum inrush current: 50 mA Min. switching current: 2 mA (24ÃVÃDC) Interrupting rating (ohmic load) max.: 1.2 W (at 24 V DC) Switching capacity min.: 48 mW Motor load according to UL 508: 1/3ÃHP, 240ÃVÃAC Switching: when the gold layer is destroyed Note: the following values are applicable if a gold layer is destroyed Contact material: AgNi Maximum switching voltage: 250 V AC/DC Minimum switching voltage: 5 V (At 24 mA) Limiting continuous current: 6 A Maximum inrush current: 16 A (20 ms, N/O contacts) Min. switching current: 5 mA (at 24ÃV) Interrupting rating (ohmic load) max.: 144 W (at 24 V DC) 124 W (at 48 V DC) 108 W (at 60 V DC) 52 W (at 110 V DC) 48 W (at 220 V DC) 1500 VA (for 250 V AC) Switching capacity: 2 A (at 24 V, DC13) 0.22 A (at 120 V, DC13) 0.11 A (at 250 V, DC13) 1.5 A (at 24 V, AC15) 1.5 A (at 120 V, AC15) 1 A (at 240ÃV, AC15) |
